Kinam Engineering Industries - A heat exchanger specialist from India, having experience of more than 35 years is a renowned name in the leading manufacturers of Shell Tube Heat Exchangers (STHE) & Corrugated Tube Heat Exchangers (CHTE).

Heat Exchangers on their own can drastically reduce fuel consumption, cut costs and reduce the carbon footprint making them an integral part of any production plant. Heat exchanger manufacturer can affect the plant’s overall efficiency, and as industries grow, the need for more efficient and improved heat exchangers is on a constant rise. As such, it is thus imperative that we learn about the history of these devices, and how they have developed over the years.

Rudimentary examples of heat exchanging devices have been found in Europe from Roman Times, where systems we would now call recuperators were used in baths. Around the turn of the first millennium, the principles for indirect heat exchange were being used for the production of pure alcohol, which still are the core principles of Heat Exchangers.

The recorded history of Heat Exchangers can be traced around the 1880s, their major applications being the food and beverage industries. It is widely recognized that the first recorded patent for a Plate heat exchanger was awarded to Albrecht Dracke of Germany in 1878.  However, the first modern and commercial examples of Heat Exchangers would be observed in the early 1900s.

Initial developments In the early 1900s:

In the early 1900s, the first known designs for Tubular Heat Exchangers were developed. These were developed due to the operational demands from power plants, where they would be used as condensers as well as feedwater heaters, both of which are still common applications. Between the late 1880s and 1920s, several developments were made for Plate Heat Exchangers (PHE),  which resulted in many patents covering its different forms, particularly its use in the pasteurization of milk.
